First, I hope this is the correct section of the forum to ask this question, otherwise I ask that this thread be moved.
I have read several studies on thermionic converter to convert heat directly into electricity because I find both the working principle and the purpose very interesting and useful. I am not here to go into too many technical details, but simply to ask what is the current state of the art of such a converter ... specifically whether we can achieve high efficiencies (I had read efficiencies of 30% for temperatures of 1000 °C, but the paper is from years ago, I think it's very low efficency ... isn't it?), whether they are used, whether it is a technology that is still being studied and especially what would be the main problems/challenges in the implementation of such a converter
If you want to refer me to the link of recent studies, I would be very grateful.
Thanks.
